Louisville , Kentucky -LRB- CNN -RRB- -- Hillary Clinton sounded a populist tone in a fiery campaign appearance Wednesday , as she continued to unveil a political message ahead of the midterm elections .

`` The other side has done everything it can to divide you , '' she told several thousand raucous fans in Louisville . `` This election is about the future . ''

Clinton 's speech comes as the former secretary of state moves back into the political sphere with a series of rallies for Democrats up this midterm cycle . On Wednesday , she rallied supporters of Alison Lundergan Grimes , who is challenging Senate Minority Leader Mitch McConnell in a high-profile race .

`` Let 's put another crack in the glass ceiling , and elect this incredible young woman to the United States Senate , '' Clinton exhorted the cheering audience .

Clinton criticized McConnell and politicians in Washington for causing gridlock and slowing economic growth , and she lamented the avalanche of money outside groups are dumping into the midterm elections .

She urged Kentuckians to send a new voice to the Senate .

Some of her biggest applause lines centered on pocketbook issues such as raising the minimum wage and equal pay .

`` Is n't it amazing that it 's 2014 , and we are still debating whether women deserve equal pay for equal work ? '' she asked . `` If there 's only one reason that will motivate you to go vote in the next 20 days , put that at the top of the list . ''

Clinton 's visit to Kentucky comes a day after the Democratic Senatorial Campaign Committee said it would stop running ads in support of Grimes .

On Thursday , Clinton heads to Michigan to campaign for Senate candidate Gary Peters and gubernatorial candidate Mark Schauer .
